Specification describing a new and Improved Plow, invented by LEWIS B.WHITE, of Norfolk, in the county of Norfolk and State of Virginia. l

Figure 1 represents a side view of my improved plow. Fig. 2 is ahorizontal section of the same on the line c c, Fig. 1. Fig. 3 isadetail longitudinal section of the plow-point 5 and Fig. 4, a sectionalside view of the weederstock.

Similar letters of reference indicate corresponding parts.

This invention relates to a new plow, which is provided with anadjustable share, moldboard, beam, and weeding attachment, in order tobe adjustable to all kinds of soil and manner of preparing the same. Theinvention consists, `irst, in providing the share and mold-board withbackWardly-projecting slotted ears, whereby they are secured to thestandard, and, owing to the slots, adjustable thereon. The inventionalso consists in providing the mold-board with detachable extensionpieces or wings; also in the use of reversible ,and up-and-downadjustable weeders, applied to a longitudinally-adjustable stockorholder; and linally, in making the beam adjustable on the standard andhandle, or vice versa, to regulate the width of furrow and theinclination of the plow-share.

Ain the drawing represents the plow-beam, pivoted by a vertical bolt, a,to the cap b of the plow-standard B. The rear end of the beam A is by apivot-bolt, d, connected with the step C' of shoe C, which is, by abolt, c, fastened to the plow-handles D, betweenwhich a rearprojectingflange, a, of shoe G extends, the same being slotted to be verticallyadjustable. By setting the shoeG up or down on the handle, the relativedirections of the beam and bottom of the plow will be varied to regulatethereby the inclination of the plow-point and the depth of draft. Thehorizontal step C' of the shoe O is slotted to receive the bolt d, toenable the beam to swing on the pivot a, and the plow-share to be movedmore or less obliquely during a straight draft. The plow-standard B ismade iiat, as shown; also its base f, on which the brace g of the'standard and the handle D rest.

E is the plow-share or point, and F the moldboard. The share has abackwardly-projecting ear, h, slotted and fastened, by a bolt, t', tothe standard, as shown in Fig. 3. The moldboard has also abaclrWardly-projecting ear, j, fastened by a bolt, 1, to the standard,as is indicated in Fig. 2. The ears h and 7' are both slotted to allowthe convenient adjustment of the share and mold-board, or else thestandard may be slotted for like purpose where the fastening-bolts passthrough it. This mode of fastening the plow is morev practical andeconomical than the ordinary method of tting the bolts through theblades, exposing theirheads on the face. G G are Win gs, applied againstthe edges of the mold-board to extend it laterally. They are, by bracesm, staples n, and pins O, fastened at the back of the mold-board, andhave the edges contiguous to the mold-board -rabbeted, as shown, toinsure a reliable connection. They can be replaced by other wings ofdifferent size when the width of the moldboard is kto be enlarged orreduced. H is the Weeder-stock, fitted over the base f .of theplow-standard, straddling the same, 'and fastened thereto. by a bolt, p.It is slotted7 to be back-and-forward adjustable, to t the position ofthe weeders to the width of the moldboard. I I are the weeder-blades,fastened to the wings r of the stock H by bolts s s. The

blades are lslotted' vertically, to be up-anddownI adjustable, and havetheir upper as well as their lower edges sharpened, so they can bereversed from one side of the stock to the other when worn on one side.

The wings of the weederlstock are or may be horizontally slotted topermit the lat-eral extension of the weeders.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The plow-share E and mold-board F, provided withthe backwardly-projecting ears h j, respectively, and united by means ofbolts i l to standard B, in the manner and for the purpose specied.

2. The sweep-stock H, litting over the base or shoe f, and adjustablysecured thereto by means of bolt p, and having the win gs r r, in

combination with the detachable and reversiport for therear end of theplow-beam, which ble sweeps I, all us and for the purpose speciisadjustabiy secured to it by means of bolt; d,

fied. all as and for the purposes specified.

3. The shoe C, provided with horizontal LEWIS B. WHITE. step c' andrear-projecting plate n, the latter Witnesses: being clamped between thehandles by means T. B. MOSHER,

of a bolt, e, and the former serving as a sup- W. A. GRAHAM.
